Dude, you need to step back. Earlier this week you messaged me asking about good beginner reptiles for you, then for your sister, basic care information that a simple google could finf, and then finally asking if I had any tips for keeping a garter snake you caught in your yard (did you really release it? Doesn't sound like it.) You need to slow WAY down. Do some serious research and find what species you really want to keep and how to keep them. Then, drop some money on a good setup with a quality thermostat and thermometer, and dial it in until it is ready for your little buddy. Finally, you can find a fantastic captive bred snake from a reputable breeder. Please dude, slow down a bit. I can tell that you like reptiles, but there is a serious commitment to them. Will you still be super pumped about your snake in a year? 5 years? 10 years? More? Please think about it.
Sorry about going off on this tangent, but I felt that this was what needed to be said. Hope that the little corns do well.
